Micropayment for storage service

I just received a bill for the very small amount of storage I had used on Amazon's Simple Storage Service (S3) during the month of July. The charge for my storage and data transfer was 4 cents!

We have talked about micropayments for years, but, until now, I had never made one.

This is a terrific example of Web services. S3 is the base service -- offering reliable, infinitely scalable storage in Amazon's data centers. But, I do not deal directly with Amazon. Jungledisk has virtual disk software that makes my S3 store look like a standard disk drive on my computer. They insulate me from S3, pay Amazon, and bill me. My payment is automatic through another service, Paypal.
